[note] request-js 筆記

request @ github

使用

/**
 * 基本的 request 使用
 **/
request('http://www.google.com', function (error, response, body) {
  // Print the error if one occurred
  console.log('error:', error);

  // Print the response status code if a response was received
  console.log('statusCode:', response && response.statusCode);

  // Print the HTML for the Google homepage.
  console.log('body:', body);
});

/**
 * 使用設定
 **/
var options = {
  url: 'http://www.pjchender.com',
  method: 'POST',
  headers: {
    'Content-Type': 'application/x-www-form-urlencoded',
    Cookie: 'put cookie here',
  },
  qs: {
    s: 'query_string',
  },
  form: {
    name: 'foo',
    address: 'bar',
  },
  formData: {
    strTargetField: 'COUNTY',
  },
};

request(options, (err, res, body) => {
  if (err) {
    throw new Error(err);
  }
  let $ = cheerio.load(body);
  console.log(body);
});

設定預設值

let request = require('request');

request = request.defaults({
  jar: true, // 將前一次 request 得到的 Cookie 自動套用到後面的 request 中
  headers: {
    cookie: 'this is cookie',
    'user-agent': 'this is user agent',
  },
});

安裝

$ npm install request
